Visible upconversion luminescence is efficiently generated in BaCl<sub>2</sub>:Ln<sup>3+</sup> (Ho<sup>3+</sup> or Pr<sup>3+</sup>) particles via excitation with broad band near-infrared part of sunlight. We observed greatly enhanced photocurrent response from the thin-film hydrogenated amorphous silicon solar cell covered with the upconversion layer of BaCl<sub>2</sub>:Ho<sup>3+</sup> phosphor, which demonstrates a prospective application for near-infrared photoresponse devices.
